EDIT: I have a Wii but I only bought like one or two games for it then it just kinda...gathered dust. Since I have a Wii U, what kind of Wii games should I get then based on my little list before? 0_0
you missed a ton of great stuff on the wii:
xenoblade chronicles: a magnificent rpg in size and scope and effort. highly recommended to any fan of the genre. remember the majesty of old 3d games, when you could see something off in the distance and the sense of accomplishment of actually arriving there? well this brought that back tenfold. the world is enormous, and fun to explore. that says nothing of the deep customization either.
phantom brave: we meet again: a tentative recommendation since the psp version (the hermuda triangle) is the most complete version of the game, and it's something that's been out on the ps2 for a decade now. still, if strategy rpgs are your bag, give it a shot. it's definitely different from others in the same genre.
fire emblem: radiant dawn: a sequel to the gamecube's path of radiance. if you never played that, you might miss out on some of the impact of the story, but it's not totally necessary to enjoy the game. fire emblem is recommended for anyone looking for a challenge in their rpgs. your character falls in battle, and they're dead for the rest of the game.
there are a couple other rpgs others may recommend that i haven't had too much time with. exclusives are pandora's tower and the last story. i haven't tried pandora's tower yet, but the last story comes from final fantasy/blue dragon/lost odyssey producer hironobu sakaguchi. i haven't gotten too far into it, but i neither love it nor hate it. maybe check out some videos and see what you think. tales of symphonia 2 is also on the platform, but since it's part of the collection on ps3, it's really not super important that you get it here. finally, sakura wars 5 is supposed to be pretty good. it's also out on ps2, but i've never played either version.
outside of rpgs:
madworld: this was platinum's first game. it's a gruesome black and white brawler. you get points for inventive kills in a sort of playground of death. once you hit the target score, you face off in a boss battle. it's a pretty good action game, and one of their overlooked titles (also seek out the rpg infinite space for the ds if you haven't already).
super mario galaxy 2: if you liked super mario galaxy, super mario galaxy 2 is like the first one except better in every way. the level design, the pacing, the power ups- all fucking great compared to the first one.
sin & punishment: star successor: this is a shmup from treasure, and just badass the whole way through. in a year where platinum released two badass action games in bayonetta and vanquish, this was up there with the rest of them for me. i mean just the
menu music is fucking rad and the game hasn't even started yet.
the legend of zelda: twilight princess: honestly, this is my favorite zelda game, and kind of a no-brainer as a general recommendation. despite a slow start, this game recovers in fantastic fashion with the best dungeons in the series.
sonic colors: the best and most complete 3d sonic game. while sonic generations has higher highs, it never had the consistency and quality in pacing sonic colors did. sonic colors successfully combines power ups with sonic's speed, and returns some platforming and exploration to a series that had been moving away from that for at least a decade.
metroid prime 3: corruption: while the first metroid prime was boring, and the second one was a mixed bag, metroid prime 3 is a pretty solid affair from start to finish. backtracking in the middle of the game unfortunately brings about a lot of load times, but the combat is quick and the aiming controls contribute to better level design. by far the best in the trilogy.
zack and wiki: a very overlooked character puzzle game from capcom. lots of inventive puzzles regarding the motion controls.
on the wii's vc there are
a lot of older rpgs. you unfortunately have to be in wii mode to get them through the wii's vc store though. so that kind of sucks. the wii u has been very slowly getting more. on the wii u's vc, the star rpg right now (and for over a year) has been earthbound.
